Help me compile procedural terrain generators!

[qubodup]

I tried out some heightmap generators to make a map for trigger rally. I failed at all but one. My test system: arch linux 32bit, gcc (GCC) 4.6.2 20111223 (prerelease)

Perhaps looking at these errors will give you an idea what I did wrong?

hme

{l Code}: {l Select All Code}

$ gcc -o terrained -g *.c -lSDL -lpthread
/usr/bin/ld: /tmp/ccqwhsFF.o: undefined reference to symbol 'sqrt@@GLIBC_2.0'
/usr/bin/ld: note: 'sqrt@@GLIBC_2.0' is defined in DSO /lib/libm.so.6 so try adding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation

terraineer
http://terraineer.sourceforge.net/ v0.3

I install the dependencies, create a /usr/bin/ncc that contains 'mono /opt/nemerle/ncc.exe $@'

I get this msg a few times:

{l Code}: {l Select All Code}

____________________________________________________________
Package gtk-sharp was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk-sharp.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk-sharp' found

but it compiles.

mono terraineer.exe throws an error of course

{l Code}: {l Select All Code}

$ mono terraineer.exe

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Nemerle, Version=1.0.0.9832, Culture=neutral, PublicKeyToken=e080a9c724e2bfcd' or one of its dependencies.

I don't know how to link? gtk-sharp...

works!

For terrained you need '-lm' (lowercase L, no quotes) on the gcc command line, which links with the standard math library.

Dunno about the rest.

Don't you mean hme not terrained?

[qubodup]

right: hme compiles into a binary called terrained. And the hint allowed me to compile successfully!
